Small platform specific bug fixes for problems found in randconfig builds.
* randconfig/mach:
ARM: ux500: don't select LEDS_GPIO for snowball
ARM: imx: build i.MX6 functions only when needed
ARM: imx: select CPU_FREQ_TABLE when needed
ARM: imx: fix ksz9021rn_phy_fixup
ARM: imx: build pm-imx5 code only when PM is enabled
ARM: omap: allow building omap44xx without SMP
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
The head-v7.S contains a call to the generic cpu_suspend function,
which is only available when selected by the i.MX6 code. As
pointed out by Shawn Guo, i.MX5 does not actually use any
functions defined in head-v7.S. It is also needed only for
the i.MX6 power management code and for the SMP code, so
we can restrict building this file to situations in which
at least one of those two is present.
Finally, other platforms with a similar file call it headsmp.S,
so we can rename it to the same for consistency.
Without this patch, building imx5 standalone results in:
arch/arm/mach-imx/built-in.o: In function `v7_cpu_resume':
arch/arm/mach-imx/head-v7.S:104: undefined reference to `cpu_resume'

The ksz9021rn_phy_fixup and mx6q_sabrelite functions try to
set up an ethernet phy if they can. They do check whether
phylib is enabled, but unfortunately the functions can only
be called from platform code if phylib is builtin, not
if it is a module
Without this patch, building with a modular phylib results in:
arch/arm/mach-imx/mach-imx6q.c: In function 'imx6q_sabrelite_init':
arch/arm/mach-imx/mach-imx6q.c:120:5: error: 'ksz9021rn_phy_fixup' undeclared (first use in this function)
arch/arm/mach-imx/mach-imx6q.c:120:5: note: each undeclared identifier is reported only once for each function it appears in
The bug was originally reported by Artem Bityutskiy but only
partially fixed in ef441806 "ARM: imx6q: register phy fixup only when
CONFIG_PHYLIB is enabled".

This moves the imx5 pm code out of the list of unconditionally
compiled files for imx5, mirroring what we already do for imx6
and how it was done before the code was move from mach-mx5 to
mach-imx in v3.3.
Without this patch, building with CONFIG_PM disabled results in:

Though commit 602bf40 (ARM: imx6: exit coherency when shutting down
a cpu) improves the stability of imx6q cpu hotplug a lot, there are
still hangs seen with a more stressful hotplug testing.
It's expected that once imx_enable_cpu(cpu, false) is called, the cpu
will be taken down by hardware immediately, and the code after that
will not get any chance to execute. However, this is not always the
case from the testing. The cpu could possibly be alive for a few
cycles before hardware actually takes it down. So rather than letting
cpu execute some code that could cause a hang in these cycles, let's
make the cpu spin there and wait for hardware to take it down.

The ldb_di[01]_podf is implemented as a clk-divider that
divides by 1 or 2. In reality, the ldb_di[01]_ipu_div
dividers divide by either 3.5 or 7. Adding a fixed factor
of 1/3.5 fixes their children's clock rates.
This should probably be converted to rate table based dividers,
once available.

The imx5 common clock migration causes a regression with smsc911x
driver on imx53-ard board, where a smsc lan9220 controller gets
connected on imx53 with EIM interface. EIM needs clock emi_slow_gate
to be functional. In the new imx5 clock driver, there is no use count
incremented for the clock by enabling it, so the framework closes the
clock at late init time and makes EIM stop working then.
Enable emi_slow_gate in clock driver initialization to fix the
regression.

This branch contains two kinds of updates: Some platforms in the process
of getting converted to device tree based booting, and the platform
specific patches necessary for that are included here. Other platforms
are already converted, so we just need to update the actual device
tree source files and the binding documents to add support for new board
and new drivers.
In the future we will probably separate those into two branches, and
in the long run, the plan is to move the device tree source files out
of the kernel repository, but that has to wait until we have completed
a much larger portion of the binding documents.

Some mxc processors have an edge_sel feature, which allows the IRQ to be
triggered by any edge.
This patch makes use of this feature if available, which skips mxc_flip_edge().

This patch completes commit 08406f5 by fixing the following issues, according to
the reference manual:
* MXC_OTG_UCTRL_OPM_BIT disables (masks) the power/oc pins if set, like H1PM and
H2PM, not the opposite.
* MXC_OTG_PHYCTRL_OC_DIS_BIT disables the oc pin if set, like H1_OC_DIS, not the
opposite.
* Typos in comments.

Two bug fixes for the previous state of the imx sparse irq changes.

Commit
544496a (ARM: imx: move irq_domain_add_legacy call into avic driver)
introduced unconditional calls to irq_find_mapping and
irq_domain_add_legacy, but it's still possible to have a .config without
CONFIG_IRQ_DOMAIN=y resulting in
CC arch/arm/plat-mxc/avic.o

While selecting CONFIG_IRQ_DOMAIN would be enough, USE_OF is the future
and implies CONFIG_IRQ_DOMAIN. So select USE_OF for ARCH_MXC and drop
other explicit selects that are superflous now.
